Barbara,
First, biological coevolution benefits the genes - not the species (...it
also tends to generate environmental complexity...)... conceivably, you
could have memetic coevolution... but...
...that assumes that the timescales of the coevolving species are
comparable... there's a big mismatch between rates of human memetic
evolution (...cultural evolution...) and extrapolated machine memetic
evolution (...uh, use commercial software evolution as a baseline...).
That's why it's a singularity.
I'm afraid that if we're not going to be content with being well-behaved
ancestors... well, we're in a pickle!
